2009 Jeep Grand Cherokee

TRACTION CONTROL LIGHT (SKIDDING CAR) FLASHES, FEELS LIKE ABS IS BEING APPLIED TO PASSENGER FRONT WHEEL EVEN THOUGH I AM NOT APPLYING THE BRAKES AND EVEN WHEN ACCELERATING. USUALLY ONLY STOPS WHEN THE EAS/BAS LIGHTS COME ON. ALWAYS WORSE ON WARM DAYS. JEEP SAYS THERES NO ISSUE BUT AFTER 5 MINUTES ON THE INTERNET, THATA CLEARLY NOT TRUE. *TR

TIRE HAD GONE FLAT TWICE FOR WITH NO DAMAGE TO THE TIRE IT SELF. WITH FURTHER INSPECTION THERE WAS A CRACK FOUND ON THE REAR FACE OF THE WHEEL STARTING FROM THE INSIDE AND WORKING OUT TO THE TIRE SEALING SURFACE. THERE IS NO DAMAGE TO THE TIRE AND NO BEND OR SCRAPS IN THE ALUMINUM WHEEL INDICATING AN IMPACT. THERE IS CORROSION IN THE CRACK WHICH WOULD LEAD ONE TO BELIEVE THIS TO BE A FATIGUE CRACK AND IT BEING IN THE WHEEL FOR SOME LENGTH OF TIME. VEHICLE WAS INSPECTED BY DEALER, PHOTOS WHERE TAKEN AND THE DEALER LEFT THE DECISION TO REPLACE THE ALUMINUM WHEEL UP TO THE REGIONAL SERVICE MANAGER. THE REGIONAL SERVICE MANAGER DENIED THE CLAIM ON THE BASIS OF WHEELS BEING A WEAR ITEM. THIS WAS RELAYED VIA THE DEALERSHIP SERVICE MANAGER. I HAVE PHOTOS OF THE WHEEL, AND THE WHEEL ITSELF IS AVAILABLE FOR INSPECTION. IT IS CLEAR THAT THIS IS NOT AN IMPACT CRACK, BUT INSTEAD A FATIGUE CRACK. AT THIS POINT IN TIME WE ARE NOT DRIVING THE VEHICLE FOR FEAR THE OTHER WHEELS MIGHT BE DOING THE SAME THING. *TR

DRIVING 2009 JEEP GRAND CHEROKEE ON HIGHWAY AT 65 MPH. RIGHT FRONT TIRE INSTANTLY WENT FLAT PRECEEDED BY A LOW TIRE PRESSURE INDICATOR. AUTO CLUB INSTALLED SPARE AND NOTED THAT THE TIRE VALVE (TIRE PRESSURE MONITOR WHEEL SENSOR) WAS GONE. TIRE DEALER CHECKED TIRE (NOW DAMAGED BEYOND REPAIR) AND FOUND THE PRESSURE SENSOR FELL INTO THE WHEEL BECAUSE THE THREADED NUT THAT HOLDS THE SENSOR IN PLACE FAILED AND SEPARATED FROM THE WHEEL WHILE DRIVING. INSPECTION OF SENSOR ASSEMBLY SHOWED CLEAR EVIDENCE OF SEVERE CORROSION TO THE THREADS WHICH ALLOWED RETAINING NUT TO SEPARATE AT HIGHWAY SPEEDS. INSPECTION BY TIRE DEALER OF ALL OTHER WHEELS SHOWED SIMILAR CONDITION. VEHICLE IS REGULARLY MAINTAINED BY JEEP DEALER SHOPS, DRIVEN PRIMARILY IN NY STATE. THIS ISSUE IS WORSE THAN DRIVING ON LOW PRESSURE TIRES AS IT OCCURS CATASTROPHICALLY. THE TIRE PRESSURE MONITOR SENSOR ON THE VEHICLE IS 100% OEM (NO DISSIMILAR METALS IN USE). CANNOT BELIEVE THERE IS NO INDICATION FROM MANUFACTURER OF THIS DEFECT OR SUGGESTED PREVENTATIVE ACTIONS.

I WAS DRIVING ON THE HIGHWAY AND THE VEHICLE PULLED AWAY AS IN DRIVING ITSELF. MY ONLY CONTROL WAS THE BRAKES. IT WAS SCARY THANK GOD NO ONE GOT HURT. ITS NOT THE FIRST TIME. I'VE BROUGHT THIS TO THE ATTENTION OF THE DEALER AND THEY TOLD ME NOTHING IS WRONG. THIS HAS HAPPENED TO ME 4 DIFF TIMES. WHEN I PUT THE CAR ON PARK THE RPM REVS UP TO 5000 RPM I HAVE TO IMMEDIATELY SHUT THE CAR OFF. THIS IS A SAFETY CONCERN AND NEEDS TO BE LOOKED INTO IMMEDIATELY. *TR

THERE IS A LEAK COMING FROM THE MAPLIGHT, AND THE A POSTS ON THE DRIVER AND PASSENGER SIDE. THE LEAK GETS WORSE THE FASTER YOU DRIVE. DEALERSHIP STATES THIS IS A KNOWN ISSUE CAUSED BY THE SUNROOF DRAINS. THE DRAINAGE TUBE GETS FROZEN OR CLOGGED AND THEN LEAKS. THIS HAS HAPPENED TWICE SINCE I BOUGHT THE VEHICLE IN OCTOBER. *TR

WHILE DRIVING ON U.S. HIGHWAY 270 IN ARKANSAS THIS DATE, MY 2009 JEEP GRAND CHEROKEE EXPERIENCED SUDDEN UNINTENDED ACCELERATION. I WAS PRESSING SLIGHTLY ON THE ACCELERATOR PEDAL WHILE GOING UP A HILL WHEN THE ENGINE WENT INTO A WIDE OPEN THROTTLE CONDITION. I WAS ABLE TO MAINTAIN CONTROL OF THE VEHICLE AND TURNED-OFF THE IGNITION, ALLOWING THE VEHICLE TO COAST DOWN TO APPROXIMATELY 45 MPH. UPON TURNING THE IGNITION BACK TO "ON" THE VEHICLE AGAIN EXPERIENCED SUA AND ACCELERATED QUICKLY TO 60+ MPH. I AGAIN TURNED THE IGNITION SWITCH TO THE "OFF" POSITION AND ALLOWED THE VEHICLE TO COAST BACK DOWN. UPON TURNING THE IGNITION BACK TO "ON", THE ENGINE WENT BACK INTO A WIDE OPEN THROTTLE CONDITION AGAIN. AFTER FOUR TRIES (TURNING IGNITION "OFF", THEN "ON", THE ENGINE RPM RETURNED TO A NORMAL OPERATING CONDITION AND I WAS ABLE TO CONTINUE WITH MY TRIP. THERE WAS NO FLOOR MAT INTERFERENCE WITH THE ACCELERATOR PEDAL. THE SPEED CONTROL SYSTEM WAS NOT ACTIVATED. I AM A PILOT WITH 500 HOURS OF FLIGHT TIME AND RECENT ANNUAL CHECK RIDE QUALIFICATION/TRAINING TO HANDLE EMERGENCY SITUATIONS. HAD MY WIFE OR THE AVERAGE DRIVER BEEN OPERATING THE CAR, THERE WOULD LIKELY HAVE BEEN A SERIOUS ACCIDENT. THE VEHICLE SIMPLY WENT BERSERK. *TR

AS I WAS DRIVING MY 2009 JEEP GRAND CHEROKEE ON A HIGHWAY AT APPROX 70 MPH MY LEFT REAR TIRE INSTANTLY WENT FLAT IMMEDIATELY FOLLOWING A LOW TIRE PRESSURE INDICATOR. WHEN I STOPPED MY CAR TO CHECK THE FLAT I NOTICED THAT THE TIRE VALVE (TIRE PRESSURE MONITOR WHEEL SENSOR) WAS GONE. WHEN I CHANGED THE TIRE I REALIZED THE PRESSURE SENSOR FELL INTO THE WHEEL BECAUSE THE THREADED NUT THAT HOLDS THE SENSOR IN PLACE FAILED AND BROKE IN TWO CAUSING THE TIRE TO LOOSE ALL ITS AIR AT ONCE. I CHECKED THE RETAINING NUTS ON THE REMAINING WHEELS TO DISCOVER THEY WERE ALL CRACKED BADLY AND COULD FAIL AT ANY TIME. I LATER LEARNED FROM THE DEALER THAT CHRYSLER HAS UPDATED THE PART NUMBER TO A NEW RUBBER VALVE SENSOR, AND THE SENSOR I HAVE IS NO LONGER AVAILABLE. CHRYSLER KNOWS ABOUT THE PROBLEM BUT TO MY SURPRISE HAS NOT ISSUED A TECHNICAL SERVICE BULLETIN OR A RECALL. WHAT IF IT HAD BEEN A FRONT TIRE THAT WENT FLAT CAUSING AN ACCIDENT RESULTING IN INJURY OR DEATH TO MYSELF OR SOMEONE ELSE? I'VE CALLED CHRYSLER CUST ASSISTANCE AND AM WORKING IT OUT WITH THEM CURRENTLY. BUT FROM WHAT I'VE GATHERED SO FAR THEY DON'T SEE THIS AS A SAFETY ISSUE. TO ME THIS IS A HUGE LIABILITY ISSUE, AND AN EVEN BIGGER SAFETY CONCERN. *TR
